This is pretty interesting as I have the Kenwood Sovereign systems that uses the Entre and can control 3 - 400 (+3 rental slots) changers (DV5900M or DV5050M). Kenwood uses OpenGlobe/Escients to look up the information AND the coverart. I noticed on the brochure that this doesn't look up coverart. The OG/e system works fairly well. There is software now to edit/add_to the information when OG doesn't find it. Seems like the ReQuest system may have couple features like looking at your movies by director or actor. The interface, otherwise, does not seem that impressive.
